Publication rate and factors associated with the publication of papers submitted to the National Scientific Congresses held by the Peruvian Medical Student Scientific Society between 2010 and 2014

Introduction: The National Scientific Congress (NSC) is an annual event held in Peru in which medical students from all over the country present their research work. Objectives: To determine the publication rate in indexed scientific journals of research papers submitted to the NSCs held between 2010 and 2014, as well as the factors associated with their publication, and to describe the characteristics of the published papers. Materials and methods: Retrospective study in which 407 abstracts of research papers were reviewed. A publication time window of 6 years (from submission) was considered. A bivariate analysis was performed to assess differences between categorical and numerical variables using the chi-square and Mann-Whitney U tests, respectively. In addition, a multivariate analysis was performed using Poisson regression models (a crude and an adjusted model), calculating relative risk (RR) values with their respective 95% confidence intervals (95%CI) to determine the factors associated with the publication of papers. A significance level of p<0.05 was considered. Results: The publication rate and the median time until publication were 23.83% (95%CI: 19.93-28.23) and 14 months (IQR: 5-23), respectively. In the bivariate analysis, the year of submission and the number of advisors with experience in research that participated in the research paper were associated with the publication of the study (p=0.020 and p=0.007). In the multivariate analysis, it was found that papers with one advisor or those with two or more advisors were 2.19 and 2.61 times more likely to be published than those without advisors (RR=2.19, 95%IC: 1.10-4.36 and RR=2.61, 95%CI: 1.28-5.33, respectively). Conclusions: Nearly a quarter of the papers were published in a scientific journal and the participation of one or more advisors with research experience significantly increased the probability of publication.

Introducción. El Congreso Científico Nacional (CCN) es un evento anual realizado en Perú en el que estudiantes de medicina de todo el país presentan sus trabajos de investigación. Objetivos. Determinar la tasa de publicación de los trabajos de investigación presentados en las ediciones del CCN realizadas entre 2010 y 2014 en revistas científicas indexadas y los factores asociados a su publicación y describir las características de los trabajos publicados. Materiales y métodos. Estudio retrospectivo en el que se revisaron 407 resúmenes de trabajos de investigación. Se consideró una ventana de tiempo de publicación de 6 años (a partir de la presentación). Se realizó un análisis bivariado para evaluar las diferencias entre las variables categóricas y numéricas con las pruebas chi-cuadrado y U de Mann-Whitney, respectivamente. Además, se realizó un análisis multivariado mediante modelos de regresión de Poisson (uno crudo y uno ajustado), calculando valores de riesgo relativo (RR) con sus respectivos intervalos de confianza al 95% (IC95%) para determinar los factores asociados con la publicación de los trabajos. Se consideró un nivel de significancia de p<0.05. Resultados. La tasa y la mediana de tiempo de publicación fueron 23.83% (IC95%: 19.93-28.23) y 14 meses (RIC: 5-23), respectivamente. En el análisis bivariado, el año de presentación y el número de asesores con experiencia en investigación que participaron en el trabajo de investigación se asociaron con la publicación de los trabajos (p=0.020 y p=0.007). En el análisis multivariado, se encontró que los trabajos con un asesor o aquellos con dos o más asesores tuvieron una probabilidad de publicación 2.19 y 2.61 veces mayor que los que no tenían asesor (RR=2.19, IC95%: 1.10-4.36 y RR=2.61, IC95%: 1.28-5.33, respectivamente). Conclusiones. Casi una cuarta parte de los trabajos se publicaron en una revista científica y la participación de un o más asesores con experiencia en investigación incrementó significativamente la probabilidad de publicación.

Accessibility to student publication in dental journals in the world

Scientific research and publication play an important role during the training of dentists, but one of the most outstanding barriers is the authorship conditions of the journals. Aim: The objective of the study was to determine the accessibility to student publication in dental journals in the world. Methods: A retrospective study was carried out. 208 journals indexed in Scimago Journal & Country Rank that met inclusion and exclusion criteria were included. The instructions for the authors were reviewed, an email was subsequently sent to the journal contact and articles with student affiliation were searched in the database of each journal. For the analysis of the descriptive statistical data of frequencies and percentage, the IBM SPPS Statistics Standard Edition 22 program was used. Results: 208 journals were included, 77.67% accepted the student publication without condition. The United States, United Kingdom and India were the countries with the highest number of journals with student participation. Likewise, the journals of Q4 (85.70%), Q3 (85.40%) and Basic Sciences (100%), Dental Education (100%), Endodontic (100%), Geriatrics and Gerontology (100%) and Public Dental Health (100%), mostly accepted student authorship.

Resultados: Se evaluaron nueve revistas y en tres no se encontraron artículos con autoría estudiantil. Se publicaron 889 artículos, de los cuales el 3,49 por ciento tuvo participación de estudiantes. International Journal of Odontostomatology (5,41 por ciento) fue la revista con más artículos con autoría estudiantil. El 67,74 por ciento de los artículos fueron originales. Los autores estudiantiles brasileños y peruanos publicaron igual número de artículos (n = 8). El 19,35 por ciento de los artículos investigó temas de cirugía maxilofacial. Tres artículos estuvieron afiliados a la peruana Universidad Nacional Mayor de San Marcos. Conclusiones: La producción científica estudiantil en las revistas odontológicas indexadas en SciELO es baja y se concentra principalmente en los artículos originales(AU)

Introduction: Publishing articles during undergraduate training makes it possible for students to complete the research process and develop skills useful for graduate education. Objective: Describe students' scientific production in dental journals indexed in the SciELO collection during the years 2018 and 2019. Methods: A cross-sectional observational descriptive study was conducted in which articles were the units of analysis. The journals considered were those indexed in the collection when the search was performed and those including articles containing information related to the academic degree of authors. The variables considered were journal name, impact factor, articles with students' participation, year of publication, languages, typologies, topics, number of students per article, authorship types and modes, countries, universities and citations. Results: Nine journals were evaluated, three of which did not contain any article of student authorship. A total 889 articles were published, with students participating in 3.49 percent of them. The International Journal of Odontostomatology (5.41 percent) was the journal with the largest number of articles of student authorship. 67.74 percent of the articles were original. Brazilian and Peruvian student authors published the same number of articles (n = 8). 19.35 percent of the articles dealt with topics related to maxillofacial surgery. Three articles were affiliated to the Peruvian National University of San Marcos. Conclusions: Students' scientific production is low in dental journals indexed in SciELO, and is mainly composed of original articles(AU)

Discordancias de autoría en las publicaciones de los trabajos presentados en los congresos científicos nacionales de estudiantes de Medicina / Authorship inconsistencies in the publication of papers presented at medical students' national scientific conferences

Existe un incremento de faltas éticas en las publicaciones científicas, entre ellas las irregularidades de autoría. Con el objetivo de identificar la discordancia en el número de autores y sus factores asociados en los trabajos realizados por estudiantes de Medicina del Perú, se realizó un estudio transversal que incluyó a todos los trabajos publicados en una revista científica luego de su presentación en los congresos científicos nacionales de estudiantes de Medicina del año 2010 al 2014. Se evaluó la discordancia en el número de autores entre la presentación del trabajo al Congreso Científico Nacional y el artículo publicado. Para cuantificar la asociación con los posibles factores asociados se elaboraron modelos crudos y ajustados utilizando la regresión de Poisson detalle. Se revisaron 97 trabajos publicados en revistas científicas, en los cuales se encontró que el 53,6 por ciento (n = 52) presentó discordancias de autoría, lo que se incrementó significativamente cuando el autor corresponsal era el asesor (RP: 1,51, IC 95 por ciento,10‒2,08, p = 0,012) y cuando el diseño del estudio era experimental (RP: 1,54, IC 95 por ciento: 1,13‒2,11, p = 0,006). Más de la mitad de los trabajos publicados por estudiantes de Medicina de Perú presentó discordancias de autoría, lo que podría responder a la ocurrencia de autoría honoraria, fantasma o ambas faltas(AU)

Scientific publication is experiencing an increase in ethical breaches, among them authorship irregularities. A cross-sectional study was conducted of all the papers published in a scientific journal after their presentation at medical students' national scientific conferences in Peru in the period 2010-2014, with the purpose of identifying inconsistencies in the number of authors and their associated factors. The evaluation focused on inconsistencies in the number of authors in the paper presented at the national scientific conferences and the published version. Poisson regression analysis was used to develop crude and adjusted models to quantify the association with the possible related factors. Review of 97 papers published in scientific journals found authorship inconsistencies in 53.6percent (n = 52), a figure that increased significantly when the corresponding author was the advisor (AR: 1.51, CI 95percent: 1.10‒2.08, p = 0.012) and when the study was experimental (AR: 1.54, CI 95percent: 1.13‒2.11, p = 0.006). More than half of the papers published by medical students in Peru contained authorship inconsistencies, which could suggest the occurrence of honorary and/or ghost authorship(AU)

Relación entre factores socioeconómicos y salud bucal en estudiantes de una zona rural peruana / Socioeconomic factor in relation to oral health in students of a Peruvian rural area

ABSTRACT Introduction: The oral health of students from rural areas is a priority public health problem in Peru. Objective: To determine socioeconomic factors in relation to oral health in students from a rural Peruvian area. Methods: Descriptive cross-sectional observational study. The sample consisted of 604 students from a rural Peruvian area selected for convenience, meeting criteria of inclusion and exclusion, following ethical standards in scientific research. Socioeconomic factors were assessed using a structured questionnaire and the oral health using an epidemiological record with the indicators: DMFT index, Significant Caries Index (SiC), Simplified Oral Hygiene Index (OHI-S), Index of clinical consequences of untreated dental caries (PUFA). The evaluation was performed with natural light by calibrated observers. The data was analyzed in the program STATA 14 through frequency distribution tables and graphics. The relationship of each of the socioeconomic factors with the experience of dental caries was evaluated by the simple binary logistic regression tests. Results: The prevalence of dental caries was 85, 26 percent (DMFT = 6, 60 SiC=7, 23). The most frequent oral hygiene condition was regular, the prevalence of untreated tooth decay was 61.75 percent. Conclusions: The level of illiterate instruction, family responsibility and independent parental occupation showed a statistically significant association with their children's dental caries experience in a rural Peruvian area.

Asociación entre la pandemia de COVID-19 y las tendencias de búsqueda en internet en Latinoamérica / Association between the pandemic COVID-19 and internet search trends in Latin America

La enfermedad COVID-19 ha puesto en emergencia sanitaria al mundo. La búsqueda de información a través de internet refleja en gran medida el interés de las personas acerca de esta pandemia. El presente estudio tuvo como objetivo determinar la asociación entre el volumen relativo de búsqueda del término combinado [coronavirus + covid-19 + nuevo coronavirus + covid + SARS-CoV-2] y el número de casos confirmados y de muertes diarias por la COVID-19. Se utilizó Google TrendsTM para proporcionar datos sobre el volumen relativo de búsqueda en Google de los términos seleccionados y compararlos con el número de casos confirmados y de muertes diarias por la COVID-19 en los 10 países más afectados de Latinoamérica, reportados por el panel de control de la Organización Mundial de la Salud. El período de evaluación fue del 01 de enero al 14 de junio del año 2020. Para obtener la asociación de las variables cuantitativas se utilizó el coeficiente de correlación de Spearman, con un nivel de significancia (p≤ 0,05). Se encontró una correlación positiva y significativa (p< 0,001) entre el volumen relativo de búsqueda del término combinado con el número de casos confirmados y de muertes cada día por la COVID-19. Por lo tanto, se puede utilizar un modelo basado en el interés de búsqueda en internet para predecir el desarrollo y el momento pico del brote de la COVID-19(AU)

Causas de rechazo de donantes de sangre de un hospital del sur peruano / Reasons for blood donor deferral in a Southern Peruvian hospital

Introducción: La donación de sangre salva vidas, por lo que la seguridad de la sangre es lo más importante de todo el proceso. La localización demográfica conduce a tener causas específicas de diferimiento. Vivir en zonas altoandinas produciría cambios adaptativos hematológicos. Es por esta razón que resulta importante conocer las causas de rechazo y así poder reorientar los programas de promoción de donación de sangre. Objetivo: Determinar las causas de rechazo de donantes de sangre de un hospital del sur peruano a 3825 m. s. n. m. Métodos: Se realizó un estudio transversal, de corte retrospectivo, sobre las causas de rechazo de posibles donantes de sangre del Hospital III EsSalud, Juliaca. Se analizaron los registros de predonantes que fueron rechazados, desde enero del 2014 a diciembre del 2018. Los datos se analizaron en el programa STATA v.14. Resultados: De los posibles predonantes seleccionados (4057), 1699 (41,87 por ciento) fueron mujeres y 2358 (58,13 por ciento) fueron varones. Fueron diferidos 1458 (41,87 por ciento), los varones tuvieron la tasa de rechazo más alta 882 (60,49 por ciento) en comparación con las mujeres 576 (39,51 por ciento). La polieritrocitemia fue la causa más frecuente de rechazo 669 (45,8 por ciento). Conclusiones: La tasa de rechazo fue moderada (35,93 por ciento) y la principal causa, fue el hematocrito alto (68,4 por ciento), seguido por el bajo (6,8 por ciento).

Introduction: Blood donation saves lives. Blood safety is thus the most important factor throughout the whole process. Demographic location accounts for specific reasons for deferral. Living in high Andean areas causes adaptive hematological changes. Therefore, it is important to be aware of the reasons for deferral with a view to reorienting blood donation promotion programs. Objective: Determine the reasons for blood donor deferral in a Southern Peruvian hospital 3 935 m amsl. Methods: A retrospective cross-sectional study was conducted of the reasons for deferral of potential blood donors in EsSalud III Hospital in Juliaca. An analysis was performed of the records of pre-donors deferred from January 2014 to December 2018. The data were processed with the software STATA version 14. Results: Of the potential pre-donors selected (4 057), 1 699 (41.87 percent) were women and 2 358 (58.13 percent) were men. A total 1 458 (41.87 percent) were deferred. Men had the highest deferral rate with 882 (60.49 percent), whereas the rate for women was 576 (39.51 percent). Polyerythrocythemia was the most common reason for deferral with 669 (45.8 percent). Conclusions: The deferral rate was moderate (35.93 percent) and the main reason was high hematocrit (68.4 percent), followed by low hematocrit (6.8 percent)(AU)
